To all whom it may concern: piston 12 being movable longitudinally in Be it known that I, JOSEPH WV. DURKEE, the end of the c'ylinder 2 adjacent to the a citizen of the United States of America, nozzle 3, and over a port era-outlet opening and a resident of the borough of Brooklyn, 13 adjacent to one end of the cylinder 2.

The valves 18 and 39 nying drawing in longitudinal section. 18' each has a slight longitudinal play in its i 1 indicates in longitudinal section a 'suitvalve casing 15 or 15',.and when one of the able fire extinguishing liquid containing revalves 18 and 18 closes one of the suction ceptacle as here shown, preferably consistpipes 14 and 14', the other pipe 14 or 14 is ing of an oblong metalliccasing'with apipe open. It Wlll be seen that by means of this 5 2 located within the same andextending construction that when the casing l is (lifrom end to end thereof and having mountrected with the dlscharge nozzle downward, ed on one end thereof a nozzle 3 projecting the valves 18 and 18 will be inthe position through one end of the casing 1, and formed shown in the drawing, the suction pipe 14 with the chamber 4 at its inner end having being open and communicating with the a niouth 5 which is adapted to be closed by pipe 16 and the other'suction pipe 14 be the ball valve 6 located in the chamber 4, ing cut oil from the pipe, 16 by the valve and prevented from closing the" nozzle 3 in 18 closing the upper end of the pipe 16. the discharge of theliquid from within relVhen the container is used in an inverted ceptacle 1, by a pin 7 extending acrossthe position from that shown in the drawings 45 nozzle 3 adjacent to its contracted portion the position of valves 18, 18! will of course or neck 8, so that in the discharge of the be reversed and the liquid will be drawn up liquid from receptacle 1, it can pass freely through pipe 14.

The end of the receptacle 1, opposite to tion the liquid will be drawn in through 50 that in which is located the nozzle 3, is both pipes 14, and 14. It is of course asclosed by a plug or bushing 9 through which sumed that sufficient liquid is in the liquid extends a piston rod 10,having, on its outer receptacle to feed to both pipes 14 and 14 end a handle 11 and on its inner end a piswhen in horizontal position.

ton 12, the rod 10 extending through -the Mounted on the pipe 2 is a third 5 'pipe 2, which serves as a cylinder and the 'valve casing 19, and connected at one'110' end thereof is the end of a pipe 20,

the other end of the pipe being connected with the pipe 16 between its when liquid attempts to pass into pipe 2O,

and which permits the liquid to pass from pipe 20, being held from closing the open end 24 of casing 19 by a pin 25 adjacent thereto. The receptacle 1 is filled through a short neck on its inner end which is closed by a cap 26. The receptacle is provided with a suitable loop or handle 27 to hang it up with when not in use. The piston 12 when not in use is located in the position shown thereby, preventing the escape of any liquid through nozzle 3. In order to prevent any accidental discharge of the liquid by the piston being moved out of its normal position a suitable lock is provided as for example the cap or sleeve 28 mounted on the piston-rod 10, and having bayonet joint slots 29 which are adapted to engage pins or projections 30 on the plug 9, and by turning the piston rod 10 through handle 11, cause the cap 28 tobe interlocked with the plug ,9 and thereby preventthe piston rod 10 from being drawn out of the cylinder 2.

The operation of the device is as follows: The receptacle 1 having been filled with fire extinguishing liquid through the neck \-closed by cap 26, and the parts being in'the position shown, with the piston 12, serving as a valve to close the port 13, at one end of the pipe 21, the piston rod 10 is unlocked by turning it and is'drawn out of the cylinder 2, thereby forming a suction, which causes'the valve 6 to close, and the piston 12 passing away from port 13, opening the latter, which opens valve '22, draws down valve 18, thereby closing upper suction pipe 14 to pipe 16, and opening lower suction pipe 14 to pipe 16, and thereby allowing the liquid from the receptacle 1 to pass through lower suction pipe 14 to pipe 16. To discharge the liquid from receptacle 1, the piston rod is pushed into 0 linder 2, which causes the valve 22 to c ose valve seat 23, and pipe 20, and the valve 6 to open,

thereby freely discharging liquid through the nozzle 3. During the above described operation it is of course assumed that the nozzle end 3 is tilted slightly downwardly from the normal horizontal plane.

.It will be seen that by means of this invention a double suction pipe construction is provided in connection with a .cylinder and piston and alternately acting automatic valves whereby the device may be effectually operated in whatever position, or at whatever angle it may be held.

Having described the invention, I claim- A portable fire extinguisher ofthe kind described having a receptacle provided with a valved nozzle, a cylinder and piston, spaced valve casings to either side and adjacent the transverse center of said receptacle, an intermediate pipe connecting said casings, suction pipes connected to said casings, a rod working in said intermediate pipe and connecting said valves, and a valved pipe connected at one end to said cylinder adjacent said nozzle and at the other end to said intermediate pipe at a central point thereof, the valve in said pipe being designed to prevent a return flow. through said pipe.
